For devices with joysticks I typically use a case because I feel like they are going to get snagged or damaged but I’ve stopped using them for devices like the GXD Pixel and the RG35XXSP and I find I’m using them more often and getting my moneys worth of out of these devices.
I’ve also never been a big fan of those belt clips or holsters.
I have a few retro devices.
Those are ones I have off the top of my head. I don’t remember if I have other ones.
